New Psychoactive Substances Intoxications and Fatalities during the COVID-19 Epidemic. BIOLOGY 2023; 12:biology12020273. [PMID: 36829550 PMCID: PMC9953068 DOI: 10.3390/biology12020273] [Citation(s) in RCA: 4] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 12/09/2022] [Revised: 02/02/2023] [Accepted: 02/03/2023] [Indexed: 02/11/2023]
Abstract
In January 2020, the World Health Organization (WHO) issued a Public Health Emergency of International Concern, declaring the COVID-19 outbreak a pandemic in March 2020. Stringent measures decreased consumption of some drugs, moving the illicit market to alternative substances, such as New Psychoactive Substances (NPS). A systematic literature search was performed, using scientific databases such as PubMed, Scopus, Web of Science and institutional and government websites, to identify reported intoxications and fatalities from NPS during the COVID-19 pandemic. The search terms were: COVID-19, SARS-CoV-2, severe acute respiratory syndrome coronavirus 2, coronavirus disease 2019, intox*, fatal*, new psychoactive substance, novel psychoactive substance, smart drugs, new psychoactive substance, novel synthetic opioid, synthetic opioid, synthetic cathinone, bath salts, legal highs, nitazene, bath salt, legal high, synthetic cannabinoid, phenethylamine, phencyclidine, piperazine, novel benzodiazepine, benzodiazepine analogue, designer benzodiazepines, tryptamine and psychostimulant. From January 2020 to March 2022, 215 NPS exposures were reported in Europe, UK, Japan and USA. Single NPS class intoxications accounted for 25, while mixed NPS class intoxications represented only 3 cases. A total of 130 NPS single class fatalities and 56 fatalities involving mixed NPS classes were published during the pandemic. Synthetic opioids were the NPS class most abused, followed by synthetic cathinones and synthetic cannabinoids. Notably, designer benzodiazepines were frequently found in combination with fentalogues. Considering the stress to communities and healthcare systems generated by the pandemic, NPS-related information may be underestimated. However, we could not define the exact impacts of COVID-19 on processing of toxicological data, autopsy and death investigations.

Outcomes in patients with history of cocaine use presenting with chest pain to the emergency department: Insights from the Nationwide Emergency Department Sample 2016-2018. J Am Coll Emerg Physicians Open 2022; 3:e12618. [PMID: 35072159 PMCID: PMC8760951 DOI: 10.1002/emp2.12618] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/11/2021] [Revised: 10/24/2021] [Accepted: 11/17/2021] [Indexed: 11/12/2022] Open
Abstract
OBJECTIVES Cocaine use (CU) related chest pain (CP) is a common cause of emergency department (ED) visits in the United States. However, information on disposition and outcomes in these patients is scarce. We conducted a nationwide study to assess disposition from ED, hospitalization rates, in-hospital outcomes, and health care costs in patients with history of CU who presented to the ED with CP. METHODS We queried the Nationwide Emergency Department Sample database from 2016-2018 for adult patients with CU presenting to the ED with CP. International Classification of Diseases, Tenth Revision codes were used to identify study patients. RESULTS We identified 149,372 patients. The majority were male (76%), presented to metropolitan centers (91.3%), and had a high prevalence of cardiovascular risk factors (48.1% with hypertension, 24.4% with coronary artery disease, 18.2% with diabetes) and psychiatric illnesses (21%). Overall, 21.4% of patients were hospitalized, 68.6% were discharged from ED and 6.6% left against medical advice. Patients requiring admission were older (51.8 vs 45.0; P < 0.0001) and had a higher prevalence of coronary artery disease, peripheral arterial disease, hypertension, diabetes, and chronic kidney disease. Of those admitted, 45.7% were diagnosed with myocardial infarction (MI), constituting 9.7% of the total study population. Over 80% of these patients underwent coronary angiography and 38.6% had coronary intervention. Mortality was 1.2%. CONCLUSION CU patients who present to ED are predominantly male, are from lower economic strata, and have significant comorbidity burden. One in 5 patients requires hospitalization and has more prevalent cardiovascular risk factors and comorbidities. In-hospital mortality is low, but incidence of MI and subsequent invasive procedures is high. CU may be considered a cardiac risk factor as it is associated with high rates of in-hospital MI.

Cardiotoxicity screening of illicit drugs and new psychoactive substances (NPS) in human iPSC-derived cardiomyocytes using microelectrode array (MEA) recordings. J Mol Cell Cardiol 2019; 136:102-112.

Abstract
The use of recreational drugs, including new psychoactive substances (NPS), is paralleled by emergency department visits of drug users with severe cardiotoxicity. Drug-induced cardiotoxicity can be the (secondary) result of increased norepinephrine blood concentrations, but data on potential drug-induced direct effects on cardiomyocyte function are scarce. The presence of hundreds of NPS therefore calls for efficient screening models to assess direct cardiotoxicity. We investigated effects of four reference compounds (3-30 nM dofetilide, nifedipine and isoproterenol, and 1-10 μM mexiletine) and six recreational drugs (0.01-100 μM cocaine, 0.01-1000 μM amphetamine, MDMA, 4-fluoroamphetamine, α-PVP and MDPV) on cardiomyocyte function (beat rate, spike amplitude and field potential duration (FPD ≈ QT interval in ECGs)), using Pluricyte® human-induced pluripotent stem cell (hiPSC)-derived cardiomyocytes cultured on ready-to-use CardioPlate™ multi-well microelectrode arrays (mwMEAs). Moreover, the effects of exposure to recreational drugs on cell viability were assessed. Effects of reference compounds were in accordance with the literature, indicating the presence of hERG potassium (dofetilide), sodium (mexiletine) and calcium (nifedipine) channels and α-adrenergic receptors (isoproterenol). All recreational drugs decreased the spike amplitude at 10-100 μM. All amphetamine-type stimulants and α-PVP decreased the beat rate at 300 μM, while cocaine and MDPV did so at 10 μM and 30 μM, respectively. All drugs increased the FPD, however at varying concentrations. MDMA, MDPV and amphetamine affected cardiomyocyte function at concentrations relevant for human exposure, while other drugs affected cardiomyocyte function only at higher concentrations (≥ 10 μM). Cell viability was only mildly affected at concentrations well above the lowest concentrations affecting cardiomyocyte function. We demonstrate that MEA recordings of hiPSC-derived cardiomyocytes enable screening for acute, direct effects on cardiomyocyte function. Our data further indicate that tachycardia in patients exposed to recreational drugs is likely due to indirect drug effects, while prolonged repolarization periods (prolonged QTc interval) could (partly) result from direct drug effects on cardiomyocyte function.

Abstract
OBJECTIVE Current guidelines recommend treating patients with cocaine-associated chest pain, unstable angina, or myocardial infarction similarly to patients with traditional acute coronary syndrome (ACS). Risk stratifying these patients could potentially reduce unnecessary procedures and improve resource utilization. METHODS This is a retrospective cross-sectional analysis of 258 patients presenting with cocaine-associated ACS who underwent cardiac catheterization in a community teaching hospital between 2006 and 2015. The primary outcome was the prevalence of acute obstructive coronary artery disease (CAD) requiring percutaneous coronary intervention and coronary artery bypass grafting compared with that of patients with normal coronary or nonobstructive disease. RESULTS Of the studied population, 36% had obstructive CAD requiring intervention and 64% were found to have normal coronaries or nonobstructive disease. Significant risk factors for obstructive CAD were older age, history of CAD, diabetes mellitus, dyslipidemia, ST-segment-elevation myocardial infarction, and troponin elevation. A logistic model was developed based on these variables, applied to the studied population, and was found to have 93% sensitivity in predicting the likelihood of obstructive CAD. CONCLUSIONS Cardiac catheterization in patients presenting with cocaine-associated ACS may be overutilized. A predictive model based on clinical risk factors may help individualize patient care and reduce unnecessary invasive diagnostic interventions.

Abstract
BACKGROUND The outcomes related to chest pain associated with cocaine use and its burden on the healthcare system are not well studied. METHODS Data were collected from the Nationwide Inpatient Sample (2001-2012). Subjects were identified by using the International Classification of Diseases, Ninth Revision, Clinical Modification codes. Primary outcome was a composite of mortality, myocardial infarction, stroke, and cardiac arrest. RESULTS We identified 363,143 admissions for cocaine-induced chest pain. Mean age was 44.9 (±21.1) years with male predominance. Left heart catheterizations were performed in 6.7%, whereas the frequency of acute myocardial infarction and percutaneous coronary interventions were 0.69% and 0.22%, respectively. The in-hospital mortality was 0.09%, and the primary outcome occurred in 1.19% of patients. Statistically significant predictors of primary outcome included female sex (odds ratio [OR], 1.16; confidence interval [CI], 1.00-1.35; P = .046), age >50 years (OR, 1.24, CI, 1.07-1.43; P = .004), history of heart failure (OR, 1.63, CI, 1.37-1.93; P <.001), supraventricular tachycardia (OR, 2.94, CI, 1.34-6.42; P = .007), endocarditis (OR, 3.5, CI, 1.50-8.18, P = .004), tobacco use (OR, 1.3, CI, 1.13-1.49; P <.001), dyslipidemia (OR, 1.5, CI, 1.29-1.77; P <.001), coronary artery disease (OR, 2.37, CI, 2.03-2.76; P <.001), and renal failure (OR, 1.27, CI, 1.08-1.50; P = .005). The total annual projected economic burden ranged from $155 to $226 million with a cumulative accruement of more than $2 billion over a decade. CONCLUSION Hospital admissions due to chest pain and concomitant cocaine use are associated with low rates of adverse outcomes. For the low-risk cohort in whom acute coronary syndrome has been ruled out, hospitalization may not be beneficial and may result in unnecessary cardiac procedures.

Abstract
Cardiac troponins are the most sensitive and specific markers of myocardial injury. Cardiac troponin elevation are common in many diseases and do not necessarily indicate the presence of a thrombotic acute coronary syndrome. In clinical practice, interpretation of dynamic changes of troponin may be challenging. Troponin evaluation should be performed only if clinically indicated and must be interpreted in the context of clinical presentation, ECG changes, troponin level and kinetic. In the absence of thrombotic acute coronary syndrom, troponin retains a prognostic value. Its practical interest as a risk criteria is limited to a few situations like pulmonary embolism, pericarditis an myocarditis.

Abstract
With each successive year, the number of Emergency Department (ED) visits related to illicit drug abuse has progressively increased. Cocaine is the most common illegal drug to cause a visit to the ED. Cocaine use results in a variety of pathophysiological changes with regards to the cardiovascular system, such as constriction of coronary vessels, dysfunction of vascular endothelium, decreased aortic elasticity, hemodynamic disruptions, a hypercoagulable state, and direct toxicity to myocardial and vascular tissue. The clinical course of patients with cocaine-induced chest pain (CCP) is often challenging, and electrocardiographic findings can be potentially misleading in terms of diagnosing a myocardial infarction. In addition, there is no current satisfactory study regarding outcomes of use of various pharmacological drug therapies to manage CCP. At present, calcium-channel blockers and nitroglycerin are two pharmacological agents that are advocated as first-line drugs for CCP management, although the role of labetalol has been controversial and warrants further investigation. We performed an extensive search of available literature through a large number of scholarly articles previously published and listed on Index Medicus. In this review, we put forward a concise summary of the current approach to a patient presenting to the ED with CCP and management of the clinical scenario. The purpose of this review is to summarize the understanding of cocaine's cardiovascular pathophysiology and to examine the current approach for proper evaluation and management of CCP.

Abstract
Fibromuscular dysplasia (FMD) involving the coronary arteries is an uncommon but important condition that can present as acute coronary syndrome, left ventricular dysfunction, or potentially sudden cardiac death. Although the classic angiographic "string of beads" that may be observed in renal artery FMD does not occur in coronary arteries, potential manifestations include spontaneous coronary artery dissection, distal tapering or long, smooth narrowing that may represent dissection, intramural hematoma, spasm, or tortuosity. Importantly, FMD must be identified in at least one other noncoronary arterial territory to attribute any coronary findings to FMD. Although there is limited evidence to guide treatment, many lesions heal spontaneously; thus, a conservative approach is generally preferred. The etiology is poorly understood, but there are ongoing efforts to better characterize FMD and define its genetic and molecular basis. This report reviews the clinical course of FMD involving the coronary arteries and provides guidance for diagnosis and treatment strategies.

Abstract
A life stage perspective is necessary for development of age-appropriate strategies to address substance use disorders (SUDs) and related health conditions in order to produce better overall health and well-being. The current review evaluated the literature across three major life stages: adolescence, adulthood, and older adulthood. FINDINGS 1) Substance use is often initiated in adolescence, but it is during adulthood that prevalence rates for SUDs peak; and while substance involvement is less common among older adults, the risk for health complications associated with use increases. 2) Alcohol, tobacco, marijuana, and, increasingly, prescription medications, are the most commonly misused substances across age groups; however, the use pattern of these and other drugs and the salient impact vary depending on life stage. 3) In terms of health outcomes, all ages are at risk for overdose, accidental injury, and attempted suicide. Adolescents are more likely to be in vehicular accidents while older adults are at greater risk for damaging falls. Adulthood has the highest rates of associated medical conditions (e.g., cancer, sexually transmitted disease, heart disease) and mental health conditions (e.g., bipolar disorder, anxiety disorders, antisocial personality disorder). CONCLUSION Prolonged heavy use of drugs and/or alcohol results in an array of serious health conditions. Addressing SUDs from a life stage perspective with assessment and treatment approaches incorporating co-occurring disorders are necessary to successfully impact overall health.

Abstract
Cocaine, a natural alkaloid derived from the coca plant, is one of the most commonly abused illicit drugs. Cocaine is commonly abused by inhalation, nasal insufflation, and intravenous injection, resulting in many adverse effects that ensue from local anesthetic, vasoconstrictive, sympathomimetic, psychoactive, and prothrombotic mechanisms. Cocaine can affect all body systems and the clinical presentation may primarily result from organ toxicity. Among the most severe complications are seizures, hemorrhagic and ischemic strokes, myocardial infarction, aortic dissection, rhabdomyolysis, mesenteric ischemia, acute renal injury and multiple organ failure.

Abstract
Every year more than 500,000 patients present to the emergency department with cocaine-associated complications, most commonly chest pain. Many of these patients undergo extensive work-up and treatment. Much of the evidence regarding cocaine's cardiovascular effects, as well as the current management of cocaine-associated chest pain and acute coronary syndromes, is anecdotally derived and based on studies written more than 2 decades ago that involved only a few patients. Newer studies have brought into question many of the commonly held theories and practices regarding the etiology, diagnosis, and treatment of this common clinical scenario. However, there continues to be a paucity of prospective, randomized trials addressing this topic as it relates to clinical outcomes. We searched PubMed for English-language articles from 1960 to 2011 using the keywords cocaine, chest pain, coronary arteries, myocardial infarction, emergency department, cardiac biomarkers, electrocardiogram, coronary computed tomography, observation unit, β-blockers, benzodiazepines, nitroglycerin, calcium channel blockers, phentolamine, and cardiomyopathy; including various combinations of these terms. We reviewed the abstracts to confirm relevance, and then full articles were extracted. References from extracted articles were also reviewed for relevant articles. In this review, we critically evaluate the limited historical evidence underlying the current teachings on cocaine's cardiovascular effects and management of cocaine-associated chest pain. We aim to update the reader on more recent, albeit small, studies on the emergency department evaluation and clinical and pharmacologic management of cocaine-associated chest pain. Finally, we summarize recent guidelines and review an algorithm based on the current best evidence.

Abstract
OBJECTIVES Observational studies of patients with cocaine-associated myocardial infarction have suggested more coronary disease than expected on the basis of patient age. The study objective was to determine whether cocaine use is associated with coronary disease in low- to intermediate-risk emergency department (ED) patients with potential acute coronary syndrome (ACS). METHODS The authors conducted a cross-sectional study of low- to intermediate-risk patients<60 years of age who received coronary computerized tomographic angiography (CTA) for evaluation of coronary artery disease (CAD) in the ED. Patients were classified into three groups with respect to CAD: maximal stenosis <25%, 25% to 49%, and ≥50%. Prespecified multivariate modeling (generalized estimating equations) was used to assess relationship between cocaine and CAD. RESULTS Of 912 enrolled patients, 157 (17%) used cocaine. A total of 231 patients had CAD ≥25%; 111 had CAD ≥50%. In univariate analysis, cocaine use was not associated with a lesion 25% or greater (12% vs. 14%; relative risk [RR]=0.89, 95% confidence interval [CI]=0.5 to 1.4) or 50% or greater (12% vs. 11%; RR=1.15, 95% CI=0.6 to 2.3). In multivariate modeling adjusting for age, race, sex, cardiac risk factors, and Thrombosis in Myocardial Infarction (TIMI) score, cocaine use was not associated with the presence of any coronary lesion (adjusted RR=0.95, 95% CI=0.69 to 1.31) or coronary lesions 50% or greater (adjusted RR=0.78, 95% CI=0.45 to 1.38). There was also no relationship between repetitive cocaine use and coronary calcifications or between recent cocaine use and CAD. CONCLUSIONS In symptomatic ED patients at low to intermediate risk of an ACS, cocaine use was not associated with an increased likelihood of coronary disease after adjustment for age, race, sex, and other risk factors for coronary disease.

Abstract
INTRODUCTION AND OBJECTIVES To investigate the frequency of recent cocaine use in patients attending an emergency department for acute chest pain, to describe the clinical characteristics of these patients, and to estimate the incidence of acute coronary syndrome in this population. METHODS Observational cohort study using a standard questionnaire that includes items on recent cocaine consumption. RESULTS During a 1-year period, 1240 patients aged under 55 years presented with chest pain. Of these, 63 (5%) had cocaine-related chest pain (7% of men and 1.8% of women). These patients were younger (35+/-10 years vs. 39+/-10 years; P=.002), were more frequently male (87% vs. 62%; P< .001), and were more frequently smokers (59% vs. 35%; P< .001). Patients who had used cocaine recently had a higher incidence of acute myocardial infarction (16 vs. 4%; P< .001), especially ST-segment-elevation myocardial infarction (11.1% vs. 1.6%; P< .01). After adjusting for coronary risk factors, history of cardiovascular disease and previous treatment, the odds ratio for myocardial infarction with recent cocaine consumption was 4.3 (95% confidence interval, 2-9.4). CONCLUSIONS Cocaine-related chest pain is often encountered in emergency departments, especially in men aged under 55 years. It is associated with a four-fold increase in the risk of acute myocardial infarction. All male patients aged under 55 years with acute chest pain should be asked about cocaine use.

Abstract
Acute coronary syndromes (ACS) are due to the rupture or erosion of atheromatous plaques. This produces, depending on plaque size, vascular anatomy and degree of collateral circulation, progressive tissue ischaemia which may progress to cardiomyocyte necrosis. This may then result in cardiac remodelling. Serum biomarkers are available which can be used for diagnosis of all of these stages. Markers to detect myocardial ischaemia at the pre-infarction stage are potentially the most interesting but also the most challenging. An ischaemia marker offers the opportunity to intervene to prevent progression to infarction. The problems with potential ischaemia markers are specificity and the reference diagnostic standard against which they can be judged. To date, only one, ischaemia-modified albumin(R), has reached the point where clinical studies can be performed. The measurement of the cardiac troponins, cardiac troponin T and cardiac troponin I, have become recognised as the diagnostic reference standard for myocardial necrosis. The sensitive nature of these tests has also revealed that myocardial necrosis is also found in a range of other clinical situations, highlighting the need to use all clinical information for diagnosis of acute myocardial infarction. The measurement of B-type natriuretic peptides can be shown to be diagnostic and prognostic in both ACS and detecting the sequelae of post-infarction myocardial insufficiency. The role of the B-type natriuretic peptides in detection of cardiac failure, both acute and chronic, is well defined but remains the subject of further studies, in ACS.

Abstract
We examined the nature and extent of health problems in drug user patients initially treated in emergency departments and who were subsequently admitted to all hospitals in Ontario, using data from the Hospital Medical Records Institute (HMRI). The modified standardized morbidity ratio (modified SMR) is introduced to improve the measurement and visual display of reduced morbidity as well as excess morbidity. During 1985-86, about 75% of drug user patients entered hospital through the emergency department. There were 5077 emergency patients with primary drug use-related diagnoses and 9827 with secondary drug use-related diagnoses. Cases with poisoning diagnosis made up over 80% of all drug use cases treated in emergency departments. Cases with non-dependent abuse of drugs accounted for 8-12% of emergency drug user patients, whereas those with drug dependence accounted for about 3% of emergency drug user patients. These patients had more than three times the comorbidity experience of all hospital patients. They had excess comorbidity due to mental disorders, infectious and parasitic disorders, and injury and poisoning diagnoses. However, they had reduced comorbidity due to complications of pregnancy, childbirth, and the puerperium and from congenital anomalies and conditions originating in the perinatal period. Cocaine patients were more likely to have infectious parasitic diseases and diseases of the skin and subcutaneous tissue, while amphetamine patients were more likely to have diseases of the digestive system and of the musculo-skeletal system and connective tissue.

Abstract
AIM To compare cardiac and cerebrovascular pathology among deaths due to cocaine toxicity, deaths due to opioid toxicity and deaths from hanging that were toxicologically negative for cocaine/opioids. DESIGN Case-control. FINDINGS The cocaine group had significantly higher proportions of left ventricular hypertrophy and ischaemic heart disease than either comparison group. Coronary artery atherosclerosis was also detected in significantly higher proportions of cocaine cases than in either comparison group. The cocaine group was more likely than either comparison group to have atherosclerosis of the left anterior descending coronary artery, right coronary artery and circumflex artery. Only in the left anterior descending coronary artery did the cocaine group exhibit higher levels of moderate-severe atherosclerosis. Cocaine cases also had significantly higher levels of cerebrovascular atherosclerosis than either comparison group. CONCLUSIONS Levels of cardiac and cerebrovascular pathology were higher among cocaine users than either comparison group. The high levels of cardiac and cerebrovascular pathology seen among cocaine cases do not appear to be artefacts of a drug-dependent life-style, but relate specifically to cocaine.

Abstract
Cocaine-associated chest pain is a clinical entity that crosses all socioeconomic groups and hence will be encountered by many physicians. The initial evaluation and treatment of cocaine-induced chest pain are similar to those of patients who have non-cocaine-induced chest pain, but there are several notable exceptions. This article reviews the pathophysiology, evaluation, management, and disposition decisions unique to patients presenting with cocaine-induced chest pain.

Abstract
Current estimates establish that more than 30 million people in the United States use cocaine. Cardiovascular complaints commonly occur among patients who present to emergency departments(EDs) after cocaine use, with chest pain the most common complaint in several studies. Although myocardial ischemia and infarction account for only a small percentage of cocaine-associated chest-pain, physicians must understand the pathophysiology of cocaine and appropriate diagnostic and treatment strategies to best manage these patients and minimize adverse outcomes. This article reviews the pharmacology of cocaine, its role in the pathogenesis of chest pain with specific emphasis on inducing myocardial ischemia and infarction, and current diagnostic and management strategies for cocaine-associated chest pain encountered in the ED.

Abstract
The pathophysiology of cocaine leading to myocardial ischemia is multifactorial. Given the paucity of well-designed clinical studies, treatment is directed toward the potential mechanisms involved in the development of myocardial ischemia. Fortunately, morbidity and mortality in this patient population are low, and the vast majority of patients will not suffer AMI or other cardiac complications. Long-term prognosis is excellent for those who abstain from continued cocaine use.

Abstract
The cardiac troponins are integral components of the myofibrillary apparatus and they regulate muscle contraction. The measurement of cardiac troponins has replaced other biomarkers for the specific detection of myocardial necrosis and for the diagnosis of myocardial infarction. The tissue specificity plus sensitivity of the measurement technology has meant that cardiac damage can be detected in circumstances other than conventional acute coronary syndromes. The ability to specifically detect cardiac damage as part of multiple organ failure in intensive care patients has been shown to provide prognostic information, but it is unclear whether this is a dependent or an independent marker of outcome.

Abstract
AIM To ascertain the demographic characteristics, circumstances of death, toxicological results, and major autopsy findings of cocaine-related fatalities. DESIGN Inspection of the coronial records of all cocaine-related deaths that occurred in New South Wales, Australia between 1 January 1993 and 31 December 2002. SETTING New South Wales, Australia. FINDINGS 146 cases were identified. Cocaine was implicated in the direct cause of death in 86% of cases, an antecedent cause in 8% and a significant condition contributing to death in 7%. The mean age of decedents was 34.1 years, and 84% were male. Half were employed, and 26% were in professional employment. The predominant route of administration was injection (86%), however nasal (8%), oral (3%), smoking (1%), and anal (1%) administration were all recorded. The most common location of death was a private home (53%). No intervention occurred prior to death in 82% of cases. The median blood benzoylecgonine concentration was 0.40 mg/L (range 0.00-20.00 mg/L). Cases had a mean of 3.5 drugs, with morphine (79%) the most common co-occurring drug. In 5% of cases cocaine was the sole drug detected. Cardiac pathology was noted in 57% of cases, most commonly coronary artery atherosclerosis (39%) and cardiac hypertrophy (14%). In 15% of cases moderate to severe arterial occlusion was noted. Cerebrovascular pathology was noted in 22% of cases, most commonly cerebrovascular atherosclerosis (10%). CONCLUSIONS Cocaine-related deaths are a significant clinical problem in New South Wales.

Abstract
Sickle cell disease is considered protective against large vessel coronary artery disease. Although sickle cell patients do develop myocardial degeneration and fibrosis at a higher rate than age-matched controls, they rarely suffer from an acute myocardial infarction. We present a case of a 29-year-old man with sickle cell disease who presented with an acute non-ST segment myocardial infarction. In sickle cell patients who present with chest pain as an element of their sickle cell crisis, the clinician must consider acute myocardial infarction in the differential along with more common entities like acute chest syndrome.

Abstract
AIM To investigate the frequency of non-fatal cocaine overdose, and responses to overdoses, among injecting and non-injecting cocaine users. DESIGN Cross-sectional study. SETTING Sydney, Australia. PARTICIPANTS Two hundred current cocaine users. MEASUREMENTS Structured interview. FINDINGS Thirteen per cent of the sample had overdosed on cocaine, 7% in the preceding 12 months. Cocaine injectors were more likely to have overdosed, both ever (17 v 6%) and in the preceding 12 months (9 v 3%). The most common symptoms of overdose were palpitations (68%), intense sweating (44%) and seizures (40%). The use of other drugs in combination with cocaine prior to the most recent overdose was prevalent (64%), most commonly opioids (40%), alcohol (24%) and cannabis (24%). Those who had overdosed were more likely to be female, had longer cocaine use careers, had used more cocaine in the preceding month and preceding 6 months, had higher levels of cocaine dependence and more extensive polydrug use. Twenty-four per cent had witnessed a cocaine overdose, 13% in the preceding 12 months. Injectors were more likely to have witnessed overdoses, both ever (35% v 8%) and in the preceding 12 months (20% v 3%). CONCLUSIONS Experience of, and exposure to, overdose were not rare events. Cocaine users need to be aware of the possibility and nature of overdose, and that cocaine overdose can occur irrespective of method of use. There is a need to emphasise the potential danger of combining cocaine with other drugs.
